Enter the following command to change Node 1 from standby mode to active mode:

failoverUtil setServer active

Verifying

Using the hostname or IP address of the virtual eth0:0 interface, log in to the Administration Center of each node, and verify that the correct failover deployment mode (active or standby) appears at the top of the page.

Troubleshooting Tips

If the Administration Center in both nodes displays "Failover deployment. Standby server," something may have interrupted the process initiated in Step 12. To resolve this issue, see the failoverUtil setServer command description.

During this process, you may see several error messages. These error messages are expected behavioor and informational only. The final message of the command explicitly says if the command ran successfully or not.

Procedure

Install the second Application Server (Node 2), ensuring the following:

To reduce system downtime during this procedure, enter the Node 2 eth0:0 (or any valid and currently unused) IP address and hostname when you configure "Ethernet Port 1(device eth0)" on the Network Setup page.

This configuration is temporary; you will change the eth0 IP address and hostname to the correct value later in this procedure.

Node 1 and Node 2 server times must be synchronized with each other.

Log in to the CLI of Node 1.

If you are logging in remotely, use the Node 1 eth0 IP address or hostname.

Enter the following command to change Node 1 from standby mode to active mode:

failoverUtil setServer active

Verifying

Using the hostname or IP address of the virtual eth0:0 interface, log in to the Administration Center of each node, and verify that the correct failover deployment mode (active or standby) appears at the top of the page.

Procedure

Take note of any changes you make on pages or fields that are labeled as:

Copied

Server-specific

Partially replicated

If you made changes to any copied pages or parameters, perform the following steps:

Log in to the CLI of the active server.

If you are logging in remotely, use the eth0 IP address or hostname.

Enter the following command to compress and transfer the files from the active server to the standby server:

failoverUtil copyConfigFiles

Log in to the CLI of the standby server.

If you are logging in remotely, use eth0:0 IP address or hostname.

Enter the following command to decompress the transferred files and put them in the correct directories on the standby server:

failoverUtil restoreConfigFiles

If you made changes to any server-specific pages or parameters, perform the following steps.

Tip: If your workstation screen is large enough to accommodate two full web browser windows without overlapping, you can simultaneously view the Administration Center for both the active and standby servers. This may help you configure the server-specific parameters to match between the active and standby servers.

Go to http://standby-eth0:0/admin/.

Use either the hostname or IP address of the virtual eth0:0 interface of the standby Application Server.
